Observation of c-axis Magnetization at Low Temperatures in Weak Ferromagnet FeBO Reveals a Spin-Reorientation Transition

Jacob Franklin, Jacob Pfund, Joshua Bedard +4

The weak ferromagnet FeBO is well known for being a unique system for modelling and testing magnetic dynamics primarily due to relatively simple and localized magnetic structur…

Picoscale Magnetoelasticity Governs Heterogeneous Magnetic Domains in a Noncentrosymmetric Ferromagnetic Weyl Semimetal

Bochao Xu, Jacob Franklin, Hung-Yu Yang +2

Magnetic Weyl semimetals are predicted to host emergent electromagnetic fields at heterogeneous strained phases or at the magnetic domain walls. Tunability and control of the topol…

Giant Grüneisen parameter in a strain-tuned superconducting quantum paraelectric: A consequence of the vanishing ferroelectric phonon energy

Jacob Franklin, Bochao Xu, Donovan Davino +3

Superconductivity and ferroelectricity are typically incompatible because the former needs free carriers, but the latter is usually suppressed by free carriers, unless their concen…

Directional field-dependence of tunable magnetic domains in noncentrosymmetric ferromagnetic Weyl semimetal CeAlSi

Bochao Xu, Jacob Franklin, Hung-Yu Yang +2

Dynamics and textures of magnetic domain walls (DWs) may largely alter the electronic behaviors in a Weyl semimetal system via emergent gauge fields. However, very little is known…

Mott insulating negative thermal expansion perovskite TiF3

Donal Sheets, Kaitlin Lyszak, Menka Jain +5

We characterize perovskite TiF_3, a material which displays significant negative thermal expansion at elevated temperatures above its cubic-to-rhombohedral structural phase transit…
